Abstract Poly(vinylidene fluoride‐co‐hexafluoropropylene) (PVDF‐HFP) is a highly versatile polymer used for water remediation due to its chemical robustness and processability. By incorporating metal‐organic frameworks (MOFs) into PVDF‐HFP membranes, the material can gain metal‐adsorption properties. It well known that effectiveness of these composites removing heavy metals depends on MOF's encoding extent encapsulation within polymer. In this study, it examined how micro nanoscale structure...
